NEXT_PUBLIC_ environment variables are inlined at build time by default in Next.js. To ensure the headline can be changed at runtime without rebuilding (as described in the issue #1345), you need to add export const dynamic = "force-dynamic"; before the component function. This forces the page to be dynamically rendered, allowing the env var to be read at runtime from the deployment environment.
